Outer Wilds

Progress is locked behind knowledge, not items. The clue to reach Giant's Deep or Dark Bramble is hidden on a different planet, and some puzzles require being at a specific place at a specific time in the loop. Players must remember things or take notes, and the payoff is "aha, I figured it out" rather than "I found a key."

Mark Brown groups it with Tunic, Riven and Chants of Senaar as a Metroidbrainia. He calls the place-and-time requirement "a way of proving knowledge to the game."

The design rewards methodical, single-thread puzzling and trusts the player. Chasing the quantum moon is Mark Brown's model of following one rabbit hole to its end, and he recommends Outer Wilds among indie games that engage the brain instead of running on autopilot.

He contrasts it with Blue Prince, whose random room draws stop players from following one thread. He lists it alongside Return of the Obra Dinn, Immortality and Tunic.

A central question turns the whole game into one mystery. The game opens with a time loop and asks why it happens, what happened to the Nomai and what the eye of the universe is, so every action serves the mystery.

Writer Kelsey Beachum calls it "a game about finding answers to questions about the world around you." Smaller mysteries range from a teleporting quantum moon to a missing explorer.

Players only chase what is weird, eye-catching or aimed at them. Alex Beachum found players ignored subtle clues but were drawn to the strange quantum moon and the exploding space station. Narrative worked best when directed at the player, so a Nomai statue turns to look at you and Hornfell asks what you want to do in space.

Quote: "the really hard part was figuring out how to actually get players to ask these questions and how to make them curious." He explains the techniques in a talk at the Full Indie Summit.

Total freedom from the start can overwhelm new players. Mark Brown bounced off Outer Wilds at first because of its flood of planets, people and dead ends with no first lead.

The Forgotten City's designer cites this freeze as why his game suggests an optional first lead that players can ignore at any point.

The DLC lets players turn off jump scares. The Echoes of the Eye expansion adds an option to switch off its spooky jump scares, one of several small comfort toggles Mark Brown praised in 2021.

No stated goals, so curiosity alone drives exploration. The developers deliberately give no explicit objectives about where to go or what to achieve, and achievements are hidden so they are discovered through play rather than chased.

The argument is that explicit goals can limit creativity and imagination, even after the goals are removed.

The clock pauses while players read, despite time always ticking. Outer Wilds stops its loop while text is on screen, so players can read at their own speed.

Its text is also singled out as legible, at a time when small text was the most common accessibility failure in games.

Planets change on a schedule, so when you explore matters as much as where. Sand pours from Ash Twin to Ember Twin, closing the Ember tunnels and revealing towers on Ash, while Brittle Hollow crumbles into a black hole and a comet circles the system.

Areas may be closed off by the time the player arrives, and others open only later in the loop. Mark Brown contrasts this with open worlds that change only in response to the player, like Megaton in Fallout 3 or Tarrey Town in Breath of the Wild.

A clock that ignores the player conveys the universe's cosmic indifference. Because events follow a clock, the world moves on regardless of the player's choices, progress, or even existence, which fits the game's theme.

Mark Brown says a clock was the best way to capture "the cosmic indifference of the universe."

The supernova gives the clock a fixed end and restarts the loop. Each loop ends in a supernova after 22 minutes and time returns to the start, the Groundhog Day answer to the fact that a simulated schedule can't run forever.

Majora's Mask does the same with the moon falling after three in-game days, and Dead Rising ends when the helicopter returns after 72 in-game hours. The loop turns the schedule into something to learn, then interfere with.

Keep the loop short enough that death doesn't sting, without feeling timed. Producer Loan Verneau wanted failure and death not to feel frustrating, but also didn't want players to feel they were constantly on a time limit.

A short loop in a small, dense world is also easier for players to hold as a mental model of the timeline. Quote: "we wanted to keep things short enough [that] failure and death did not feel frustrating, but we also didn't want the player to feel like they were constantly on a time limit."
